Having the opportunity of working at several project worldwide I already discovered that the idea of what is “cheap” or “expensive” may vary a lot depending on the country.

Also, huge countries like Brazil or Chile may show a relevant price dispersion depending on the area (Patagonia or Atacama desert?).

A third consideration is that, due to inflation, market situation, other project being constructed at the same time, etc. the prices may move a lot (downwards, but normally upwards) from one year to the following.

However, here you have my favorite top 5 of the most expensive price I’ve ever seen. They are totally crazy, even with all the above considerations.

Concrete: Mozambique (900€/m3)

Steel: Morocco (15€/Kg)

Embankment: Mexico (241€/m3)

Crushed stones base layer: Mozambique (450€/m3)

Overheads: Chile (50% of the project cost)

On the cheap side I'd like to mention Portugal: a country with a lot of skilled civil works companies, used to the renewable business - and with great food as well! 😉
